A normal search that attempts to following all interesting lines to some sort of stable point. 2. A q-search that is supposed to take the "stable point" and resolve any remaining tactical issues dealing with pieces that are hung, overloaded, or whatever. 3. A static evaluation that takes the positions produced by 1 + 2 above, and computes a static evaluation. It depends on the fact that all the tactical issues have been resolved by the time 1 and 2 have completed, so that it "knows" that the only considerations left are positional ones. 1 and 2 are complementary. The more you do in 1, the less you have to do in 2, for example. But for step 3, you +must+ give it "quiet positions" or it will produce bogus evaluations due to overlooked tactical opportunities.
